"I'll start once I've got a bit fitter" is the most common thing coaches hear — and the reason many people never start at all. Training is what makes you fit; waiting simply delays the process.
What's actually required
You need to be able to move for an hour with breaks. That's the whole entry requirement. Classes are self-paced in the sense that nobody forces you to keep going when you need twenty seconds and a drink.
Why martial arts fitness is different
Cardio built on a treadmill doesn't transfer cleanly to grappling, and grappling fitness doesn't transfer cleanly to pad rounds. The specific conditioning you need only comes from the activity itself, which is another argument for starting now rather than preparing first.
What to expect physically
- Weeks 1–2: you'll be out of breath quickly and sore afterwards
- Weeks 3–6: recovery improves noticeably and technique reduces wasted effort
- Months 2–3: you can complete a full session comfortably
- Beyond: fitness becomes a by-product rather than a barrier
Managing it sensibly
Two sessions a week, spaced apart, is the sweet spot for most beginners. Eat and sleep properly, tell the coach about any injury or medical condition before class, and don't try to keep up with the person who has been training for three years.
If you'd rather build up privately first, one-to-one personal training is an option — though most people find the class environment easier than they expected.
